Electrolyte tabs without 'carbonated' feel

Tested my energy drink yesterday which doesn't contain salt and minerals so I added an electrolyte tab. It had a carbonated feeling, opening the bottle for the first time even had a little pop. I guess this a normal side effect of these type of dissolvable tabs. Was worried my stomach would bloat due to the 'gas' but had a run after the bike and all felt ok. Just wondering if there are tabs (or a powder formula) that don't have this side effect.
